The Building Regulations (Northern Ireland) Multi Box HP 10 The Multi Box HP 10 is designed for operation with a split air to water heat pump. It includes a PCB (IOB-B) for the control of the following functions: NOTICE: If an IOB-B card is already installed in the system (externally or in the internal unit of the heat pump), only the central fault alarm function can be used. Check whether an IOB-B card has already been installed. 4 Standard delivery 4.1 Items included Multi Box HP 10 Cable glands, 6 pcs.

6 Installation 7 Installation 7.1 Handling circuit boards CAUTION: Always wear a a ground-connected bracelet when handling electronics. Circuit boards with control electronics are sensitive to discharges of static electricity (ESD ElectroStatic Discharge) when handled. To prevent damaging the components, special care is therefore required when handled I Fig. 5 Anti static bracelet Damage is usually latent, and a circuit board can operate correctly during commissioning but show signs of problems later. Charged objects may only be problematic if they are in close proximity to the electronics. Keep a distance of at least one metre from expanded polystyrene, protective plastic and other packaging, synthetic material (e.g. fleeces) and similar before starting work. A method for good ESD protection is a ground-connected bracelet when handling electronics. This bracelet must be put on before opening the screened metal bag/packaging or before exposing an installed board. The bracelet must be worn until the circuit board is enclosed in its screen packaging or closed electric box. Replaced, returned circuit boards must be handled in the same way. 7.2 CAN-BUS CAUTION: Interference. The CAN-BUS cable must be screened and laid with a minimum distance of 100mm separately from the power cable. CAUTION: Do not mix up the 12 V and CAN-BUS connections! The processors will be damaged beyond repair if 12 V is connected to the CAN-BUS. Ensure that the four cables which are to be connected to the contacts on the printed circuit boards are made with their corresponding markings. The printed circuit boards in the Hydrolight/Hydrocomfort unit, and accessories board if applicable, are connected via the CAN-BUS communication line. The CAN (Controller Area Network) is a system that facilitates communication between microprocessor-based modules/ printed circuit boards. A room controller is available as an accessory and must be connected by a CAN-BUS cable. Suitable cable for external laying is cable type LIYCY (TP) 2x2x0.5. The cable must be twisted pair and screened. The screen must only be earthed at one end and to the chassis. Maximum cable length is 30 m between the internal room controller and the internal Hydro unit. The CAN-BUS cable must not be routed together with the mains cable that carry 230 V or 400 V. The minimum clearance is 100 mm. Routing of these cable together with the sensor cables is not permitted. The connection between the circuit boards is by four wires, because the 12V-supply between the circuit boards must also be connected. The circuit boards have markings for both the 12V and CAN-BUS connections. 7.3 CAN-BUS cable Requirement for external CAN-BUS: Shielded line Twisted pair Minimum cross-section: 0.5 mm 2 Approved for outdoor applications Maximum length 30 m One end must be connected to the earth conductor (not GND) I Fig. 6 Using an anti static bracelet 6 Multi Box HP (2012/11)
